Bare with me on the Keybord...missing letters...lol
Okay... 10 foot putt divided by 1.35 is bout 7.5 feet of power...means on my 30 foot scale, I go one avtr movement and maybe scooch more
Say 30 foot putt, dropping 6 inches...is 24 feet of putt...24/1.4 is bout 17 feet of power
Now since I use avtr moves, not percentages or putter pal, I add a bit, take some away as needed.
Not real scientific, eh?...lol
